[LW] [LW11] MFD C120W and C90W "AIS connection lost"

[Tommy Skaarup]

I just bought a Vesper XB-8000 AIS and installed it with my Raymarine, connecting to SeaTalk with a backbone cable, a T-peace and DeviceNet adapter. I have two MFD's: C120W and C90W.
It all seamed to work well and I get AIS overlay on my MDF, but the AIS icon on the MDF is blinking as if the AIS is transmitting in pulses, and for every 30 seconds I and an alarm with the message "AIS lost connection".
I have updated the software on all my Raymarie instruments today and I the XB-8000 somftaware is fully updated too.
I tryied possible combinations of settings both on the MDF's and on the XB-8000. I also tried to connect via NMEA without any success, by connecting the following NMEA wires:
Data in: Vesper Grey to White Raymarine - Vesper Yellow to Green Raymarine
Data out: Vesper White to brown Raymarine - Vesper Green to Yellow Raymarine
By doing that I get the instrument data on the Vesper. But I don't get AIS overlay on the plotters.
Buad rates are set to: Raymarine Port2 AIS 38400 / Vesper NMEA out 38400
It is really sad that the connecting to SeaTalk with a backbone cable, T-peace and DeviceNet adapter pulsing the AIS signal on/off and coursing and alarm for every 30 seconds, because this setup seems to otherwise work very well…

I hope you are able to help and I am looking forward to hearing from you.

Kind regards, Tommy
